Abstract

A multi-stage optimal renewal planning method is proposed for an energy supply system installed into building from economic viewpoint. Based on the annualized costs method, the average annual total cost during the total evaluation period is formulated as the objective function to be minimized. This is formulated as one of the mixed-integer linear programming problem, and the numerical solution is carried out by using the GAMS/CPLEX solver. A numerical study is carried out for an energy supply system installed into an office building with total floor area of 15 000m², and the optimal renewal system is proposed as the one of installing high performance equipment properly at each optimal renewal year.
